I bought this rack after smoking 3 racks of spareribs. Even on a 22″ diameter smoker, 3 racks was a tight fit. This rack makes it VERY easy to fit 3 or 4 racks of ribs in my smoker. I chose this one because it folds flat and is stainless steel. If stuff gets baked on, I can scrub it with a wire grill brush without harming it.chefscatalog.com.
